The implementation of an extractable and leachable evaluation program is essential in addressing concerns related to rubber stoppered glass vial systems for storing therapeutic protein products. The study design successfully predicted leachables and verified the quality and safety of the glass vials, rubber stoppers, and drug products through extraction testing.
Rubber stoppered glass vial systems are widely used as primary containers for storing and delivering therapeutic protein products to patients. Addressing concerns and regulatory expectations related to the risk to biologic drug product quality and patient safety from rubber stoppered glass vial systems requires implementation of an extractable and leachable evaluation program based on material understanding, risk assessment, literature review, and a comprehensive scientifically sound analytical testing methodology. The extractable and leachable study design consisted of twelve drug products filled in twelve different size glass vials capped with laminated and nonlaminated rubber stoppers made from three different rubber formulations. Design of the model solvents was successful as they had little to no analytical interference and mimicked the formulation conditions and generated representative extractables capable of predicting leachables. The extraction conditions of time and temperature were appropriate as not to degrade the test materials or the extractable compounds, and yet generated significant quantities for identification of the extractable compounds with confidence. The extractables testing results were capable of predicting the leachable profiles of the twelve drug products. In each case, the leachable profile was a subset of the extractable profile. The organic and elemental impurities of the leachable profiles of drug products were the end-to-end verification of the quality of the glass vials, rubber stoppers and drug product lifecycles. Overall, the holistic approach was fully successful in the qualification of different vial systems as primary containers and delivery systems for different biotherapeutic products to ensure product quality and patient safety.
